Toall'inhom it may concern Be it known that we, JOSEPH DOTTL and HERBER'J; G. HART, citizens of the United States, and residing at Madison, county of Dane, State of Wisconsin, have invented a new and Improved Support, of WhlCh the following is a specification.

This invention relates to supports, principally such as are adapted to be utilizedas hangers or supports for pipes, electr c wire conduits, and the like, the general ob ect being to provide a construction of this nature which may be readily manufactured, easily applied, andwhich affords a strong substantial support for this class of devices.

One of the primary features of the invention resides in a pair of complementary straps or members each arranged to embrace and be tightened upon one side of the pipe or conduit and having its base extending through between the pipe or conduit or other supported element and that portion of the structure on which it is to be carried,

and anchoring to the latter on the opposite side of said supported element.

By this construction the anchoring devices are caused to firmly grip their support and the body portions of the straps are brought into gripping or clamping relation to the pipe or conduit when the tightening device is setup; moreover, a widesupport-. ing base is in effect secured, and the central or intermediate portions of the straps act to mutually brace one another- Another featurefof. the invention consists y in inclined widely separated tongues struck from said straps and arranged to be drawn toward each other to engage firmly with the walls of correspondingly inclined holes in the structure on'which the deviceis to be carried.

In the drawings, Figures 1 and 2 are similar longitudinal sections respectively showing one embodiment of the invention applied to brick or the like and to wood. Fig. 3 is a perspective view of the device which appears in Figs. 1 and 2. Fig. 4 is a view, .similar to Figs. 1 and 2, showing a modification applied to a flanged metal beam. Fig.

5 is a perspective viewof one of the duplicate members which go to make up the-device shown in Fig. 4. Fig. 6-is a section cor.- responding to Figs. 1 and 2 and showing a further modification. v

In the embodiment of the invention-which appears in'Figs. 1 and 2, land 1 indicate,

rod, staff or other ultimate member to be supported or an intermediate member which may in turn support something else. The construction of the pipe hanger shown will perhaps best be understood by reference to Fig. 3, from which it will be seen that it comprises two complementary main sheet metal members 3-4 from the base portions of which are struck tongues 5--6 inclined toward each other and receivable in the corresponding inclined holes or undercut openings 78 drilled or formed in the material of the structural element 1-1. These members also comprise the body portions or jaws S )-10 adapted to conform to the correspondlng side of the device 2 and terminating in end portions 11--12 pierced to receive the tightening screw or bolt 13.

The manner of adapting the one main member to the other at their intersection point may be varied, as will be better understood later; one desirable construction for this purpose appears in Fig. 3,wherein the member 3 is provided with a central longitudinal slot 15 of a length greater than the width of the part 10, and wherein the mem- I ber f-has its side portions notched over a corresponding space and to a depth sufficient to pass the associated furcation of the member 3. In assembly, the main members are swung at substantially right angles to each other to permit the body portion 10 to be inserted through the slot 15, and form one type of an interlocking connection when in the normal position shown. The hanger being placed about the element 2 and the tongues 5-6 being entered into the holes 78, it is evident that said tongues will enter farther into the holes and finally tightly engage the walls thereof as the screw 13 is tightened, and that the hanger ultimately affords a wide firm foundation or support for the element 2. In this tightening operation, the element 2 forms a fulcrum about which the straps are bent and drawn toward each other. Evidently, also, the main members may be stamped rapidly from sheet metal, and with little waste of material. In the case-of a wooden background, supplementary holding means in the form of screwslfi passing through the holes 17 may by hook sha ed ends adapted to embrace .the edges 0 the lower flange of the metal beam 21. 1

In the embodiment shown in Fig. 6, the two main members are replaced by a single member 22 whichembraces the element or article 2 and hasoppositely extending end portions 23-24 from which the tongues 2526, which correspond to the tongues 7-8, are struck. The single threaded bolt or screw 27 which suflices to simultaneously .drawthe tongues against their sockets and to grip the strap upon the element '2, is in this instance, however, placed between said element and the background.

' parts 9-11 and 10 1-2, as well as that of the member 22, may be varied widely, de-

.pending on the particular use to which the -device as a Whole is to be put.

We do not, therefore, wish to be limited exce t as indicated by the subjoined claims.

e claim 1. Means for supporting an article on a background having two holes therein whose inner ends are nearer together than their outer ends, said means including a pair of tongues or the like inclined to correspond to said holes and adapted to enter the latter,

and means for drawing said tongues toward each other to establish a firm anchorage with the walls of said holesl 2. A support comprising two main members adapted to embrace an article to be held and to fasten said article to a background, said members crossing one another in the space between the article and said background and being arranged to engage and grip the latter when drawn together, and

means on the side of said article most remote from the background for drawing said I main members together.

3. In combination with a background having'a pair of inclined holes therein whose inner end portions are nearer together than their outer end portions, an article support of substantially constant width throughout and including a pair of tongues inclined to correspond to said holes, and means for simultaneously drawing said tongues together against the Walls of said holes andclamping said support upon an article to be sup-w ported.

4. In combination with a background having a pair of inclined holes therein whose inner end portions are nearer together than their outer end portions, an article support ofsubstantially constant width throughout and including a air of ton ues inclined to correspond to said holes, an a single means for drawing said tongues together against the walls of said holes and clamping said support upon an article to be supported 5. A support comprising two crossing main members adapted to embrace an article to be held, said members extending in opposite directions through between said article and a background on which it is carried and having end portions secured to said background, and means on the side of said article most remote from the background for drawing the main members together upon said article.

6. A support including two complementary metal members having body portions adapted to conform to opposite sides of a pipe or the like, said body portions merging in base portions which extend in opposite directions through between said pipe or the It will be apparent that the shape of the,

like and a background and are fastened to the latter, and means for securing the body portions together on the side of the pipe or the like most remote from the background.

7. A pipe or conduit support including a plurality of metal straps of substantially the same width crossing each other and having their corresponding side edges arranged substantially in the same plane, corresponding ends of said straps being fastened to a supporting background, and other corresponding ends of said straps being arranged to embrace a conduit or pipe, and means for drawing said last named ends together on said )i e or conduit.

8. cans for supporting a pipe or the like on a background having two holes therein whose inner ends are nearer together than their outer ends, said means including a pair of elements inclined to each' other to correspond to said holes and adapted to extend into said holes and engage against the walls thereof to form an internal clamp, and a threaded member for drawing said elements toward each other to establish a firm anchorage with the walls of said holes.

I 9. In combination with a background hava pair of inwardly converging holes therein, an article support including a pair of inclined and converging elements entering said holes and adapted to engage the walls thereof to form the jaws of an internal clamp for holding said support firmly on the background, and a threaded member for drawing said elements together against the walls of said holes.
